There is also BBVA's Mirrorgate that was inspired by Hygieia. It looks like Hygieia has been split out from Capital One and more connectors are being produced to make it usable by people who have other tools beyond just what they use.
If you're operating in a financial services world with audit requirements and other large scale organisation joys this could be well worth a look.
We gave it a try a few years back. But between the [odd-looking docker builds](https://hygieia.github.io/Hygieia/api.html#docker-image-for-...) and the amount of work it was taking to make it work, we chose to use Grafana instead to display the result of our custom data collectors.
CapitalOne is quite exuberant about their NIH (rebranded as InnerSource) but most of the stuff they churn out isn't useful as a real open source product.
